At one point following UFC 100 this past weekend, I felt like there are a lot of new questions about who the best pound-for-pound fighter in the world is.

Georges St. Pierre certainly raised his stock with a definitive win over Thiago Alves, who was considered to be GSP’s toughest fight to date prior to UFC 100.

Brock Lesnar also deserves some consideration for his dominant performance over Frank Mir, which left many wondering who can beat him.

Here is my personalized top 10 ranking of who I feel are the top 10 overall fighters in the world. In making this list, I consider win-loss record, how convincingly the fighters have won their most recent fights, and their appeal to other fans. Well, here we go:

1. Fedor Emelianeko (30-1-1) – Heavyweight – Affliction
About a year ago, I was one of those people that claimed that Fedor was overrated and didn’t fight the best. Well, after two quick KO’s of Tim Sylvia and Andrei Arlovski, you can’t argue that Fedor is not the best. The guy has virtually never lost, with his lone loss coming on a cut. The guy never changes his expression and never makes a mistake in his fights. Until someone beats him cleanly, Fedor will be at the top of my list.

T2. Anderson Silva (23-4) – Middleweight – UFC/ Georges St. Pierre (19-2) – Welterweight – UFC
I have Silva and GSP tied because of pure dominance in their weight class. As of late, Silva has not looked his usual self in his last two fights, but part of that is because his opponents have tried to avoid his lethal strikes. GSP has been dominant in another way, controlling his opponents four as long as it takes to win. GSP has fought the tougher competition as of late, but Silva has tougher fights in his future than GSP with Dan Henderson, Damian Maia, and Nate Marquardt looming while GSP has significantly less talented fighters like Mike Swick and Martin Kampmann to deal with. A super fight between these two is appealing, but it seems like GSP is hesitant to move up in weight right now.

4. Lyoto Machida (15-0) – Light Heavyweight – UFC
Machida is unbeaten which certainly earns credibility, but in his last two fights, he has quickly finished two of the top Light Heavyweights in the world. Machida takes little to no damage in his fights and has pin-point accuracy in his strikes along with a sound jiu-jitsu game. It is tough to think of a fighter that will be able to disrupt Machida’s style, but Shogun Rua will try at UFC 104.

5. Miguel Angel Torres (36-1) – Bantamweight – WEC
It is a shame that not many know about Miguel Torres because he fights in the lesser-known WEC. But, if more fans saw Torres compete, there would be more MMA fans than ever. Torres is complete in every way and is the one fighter I can say leaves everything he has in the cage with each fight. His pacing is incredible and his diverse strikes make him one of the most entertaining fighters in the world. Torres may soon have to face the option of moving up in weight to set up potential super-fights with some of the other WEC’s top stars.

6. Brock Lesnar (4-1) – Heavyweight – UFC
I don’t like Lesnar, I think his attitude and approach to “entertaining” the fans is awful, but I can’t deny his natural ability. He has destroyed Heath Herring, Randy Couture, and Frank Mir in successive order, and he is just five fights into his professional career. As time moves on, Lesnar is only going to improve and get better in each area of fighting, which is a scary thought for every heavyweight. A fight with Fedor is the talk of the town right now, but I think Lesnar would be biting off more than he can chew with that right now. In another year or too, he certainly could dethrone “The Last Emperor”.

7. BJ Penn (13-5-1) – Lightweight – UFC
I also am not a fan of BJ Penn for his attitude on his opponents, but I also can’t deny his natural skills either. Penn’s flexibility is something no other fighter posses right now and is the reason he is considered one of the best in the world in any weight class. Penn’s record is not as strong as most, but his losses are deceiving, as he has fought many bigger fighters and given up 30 pounds or more in those fights. Losses to fighters like Machida should almost be ignored. As a lightweight, it is tough to think anyone can compete with Penn, let alone beat him.

8. Jake Shields (23-4-1) – Welterweight – Strikeforce
Shields is as hot as any fighter, winning his last 12, including his most recent win over Robbie Lawler in a bigger weight class. Shields is one of the best submission and grappling fighters in the world and many believe he could give Georges St. Pierre a run for his money.

9. Mike Thomas Brown (22-4) – Featherweight – WEC
Brown proved his worthiness to be WEC champion with a second win over Urijah Faber. Brown is a sound fighter that can stand on his feet and control on the ground. He may not be flashy, but he is dangerous anywhere in a fight and his level-headed attitude makes him a dangerous fighter.

10. Quinton Jackson (30-7) – Light Heavyweight – UFC
Jackson has beaten some of the best in the world, but his split-decision loss to Forrest Griffin set him back. You could argue that Jackson didn’t lose to Griffin and could still be UFC champion, but he hasn’t backed off, beating Wanderlei Silva and Keith Jardine since losing the belt. Next up is Rashad Evans and a win there gives him a title shot that he should have had a lot sooner.

Honorable Mention: Thiago Alves, Rashad Evans, Dan Henderson, Urijah Faber, Jon Fitch, Kenny Florian, Shinya Aoki, Nick Diaz.
